“…Several pilot plants have been established, and a series of tests have been carried out for design variables and process parameter evaluation (Wilson et al, 2004;Yokoyama, 2004;Dugas, 2006;Mangalapally et al, 2009;Kvamsdal et al, 2011). Process simulations of MEA-based solvent CO 2 capture through an absorption/stripping operation offer a valuable alternative method to help identify the key process variables and design parameters (Desideri & Paolucci, 1999;Abu-Zahra, Schneiders, Niederer, Feron, & Versteeg, 2007;Khan, Simioni, Van Zijll de Long, & Stevens, 2007;Kvamsdal et al, 2011). The ratio of solvent circulation rate to flue gas rate (L/G), identified as an important operation parameter for solvent based CO 2 capture process, has yet to be thoroughly scrutinized (Freguia & Rochelle, 2003;Hassan, 2005;Abu-Zahra, Schneiders, Niederer, Feron, & Versteeg, 2007).…”
